He's started telling me more personal stuff?

A guy who I'm getting to know (that I work with) has started telling me more personal things like how he lost his virginity and what he was like as a kid. And cause we work together I work in a cafe and he works in a pub (owned by same people) so I text him this morning asking if he wanted me to do anything and he replies with "blowie?" So I just reply with "u wish 😂" and he puts something like "nah, you're good 😉" now I wouldn't consider that flirting I'd say it's just banter?
